Multiply your multiple-choice percentage by its section weight, multiply your Create performance task percentage by the remaining weight, add the two, and divide by 100 for a weighted composite percentage.
AP Computer Science Principles Score Calculator
Estimated weighted composite score for the AP Computer Science Principles exam, from your multiple-choice and free-response section scores.
Calculating an AP CSP Weighted Composite Score
AP Computer Science Principles combines a multiple-choice exam section with the Create performance task (a program you develop and submit ahead of the exam) into a final 1–5 score, with cutoffs set only after each administration. This calculator computes your own weighted composite percentage for comparison against a released scoring guide. It covers searches like AP CSP score calculator, AP Computer Science Principles composite score, and AP CSP curve.
How the AP CSP Score Calculator Works
Formula
Weighted composite = (MCQ% × MCQ weight + FRQ% × (100 − MCQ weight)) ÷ 100
Variables
In this calculator’s fields, “multiple-choice section score” is your exam multiple-choice percentage, and “free-response section score” represents your Create performance task percentage; enter the official weighting between them.
Worked Example
Multiple-choice exam 65%, Create performance task 70%, exam weight 70%: Composite = (65 × 70 + 70 × 30) ÷ 100 = (4550 + 2100) ÷ 100 = 66.5%.
Why the Create Task Is Completed Before Exam Day
Unlike most AP exams, the Create performance task is a program you design, develop, and submit through the AP Digital Portfolio ahead of the exam date, evaluated against a published rubric — only the multiple-choice section is taken during the timed exam sitting itself.
Frequently Asked Questions
Where do I find the official weighting between the exam and the Create task?
Check the official AP Computer Science Principles Course and Exam Description published by the College Board for the current weighting between the multiple-choice exam and the Create performance task.
Can I estimate my Create task score before it’s officially evaluated?
Compare your submission against the official Create performance task rubric published by the College Board to get a rough self-assessment, though only official scoring determines your actual task score.
Does AP CSP require a specific programming language?
The Create performance task allows flexibility in programming language and tools within the College Board’s guidelines — check the official Course and Exam Description for the current requirements and allowed tools.
How can I estimate my multiple-choice percentage before official results?
Use a released scoring guide or practice exam’s official conversion rubric to translate raw points earned into an estimated percentage.
Why can’t this calculator tell me my exact 5/4/3/2/1 score?
Because the College Board sets composite-to-score cutoffs only after each exam administration and Create task evaluation cycle, based on that cycle’s overall performance, and never publishes them in advance.
Is the AP Digital Portfolio submission deadline earlier than exam day?
Yes — the Create performance task must be submitted through the AP Digital Portfolio by a deadline set before the multiple-choice exam date — check the official AP calendar for the current submission deadline.
Does AP CSP require prior programming experience?
It’s often designed as an introductory computer science course, though prerequisites can vary by school — check with your school’s course catalog or instructor for specific prerequisites.
